To all whom il may concern:

Be it known that I, lu'rnn l. Munrnr, citizen of the United States, and resident of Milwaukee, in the county of Milwaukee and State of Wisconsin. have invented certain new'and useful 1m rorenients in Flushing Devices; and 1 do hereby declare that. the following is a full, clear, and exact description thereof.

My invention has especial reference to flushing devices for closets and urinals not provided with overhead tanks, and it consists in certainpeculiarities of construction and combination of parts, as will be fully set forth'diereinafter, 1n conn ction with the accompanying drawings, an subsequently claimed; I

In the said drawings: Figure l is arepresentation, in front elevation, of a watercloset ombcdyir'g my presentinvention. Fig. 2 is a vertical sectional view, taken on the plane indicated by the line 2-2, in Figs. 1 and 3. Fig. 3 is a horizontal sectional view, taken on the lane indicated by. the line 3-3 in Fig. 2. i 4 is a vertical sectional View of the auxiliary or release ralvc,

' and its casing taken on the plane indicated b the line 4-4 in Fig. 5, and Fig. 5 is a thereto, by means of a suitabl upper part of the casing verticall ward to a. point in line with the in a-doot d,

.flow pipe) leads to a ducta lathe said i The casing 1), above\ I1, is of greater dia1n-- .casing, -'c l nder plan View, showim the two casings and pushpiece of said auxiliary or release ,valve. Referring by letter to the drawings, A re presents the bowl, and B is a, cylinder secured acked box or support 0, the said cylinder arming the lower part of the main valve casing D, which adjacent to the upper end of said B, has a lateral not or passage b t erethrough, {from which a pipe F (called the return-pipelleuds to a duct f in the cusing G of the auxiliary or release valve shown in Figs. 1 and 4. The casing D of the main valve has a duct L, which extends from the down ascribed duct 6, and thence horizonta around to a point opposite thesaid duct-1, terminating from which a pipe E (called the auxiliary valve casing G. the line of the ducts b,

, eler than the cylinder B, and forms a vertical shell, within which the main valve has movemont; the vertical part of the duct 0 is 'ireferebly formed within an exterior rib,-as thew-n in Fig. 1, and on the side opposite hereto is formed the inlet tube H connected to be operated byn suitably packed coupling 7;. with the a 1 main 1 leading: from the source of wntersupply under pressure.

The main valve comprises a lonlvl' |Qug .l of rubber or analogous material, SUC-lll'i l by a screw to a block K, the lower or nain )art of which is of considerably lrss (illlllletcr than the interior diameter of the shell or casing I), and the upper part being, reduced in diameter, forming a neck-k. This block K has a central vertical bore intherethrough, screw-threaded at each end, the lower end being closed by the described screw j which secures the plu J to the block, and the upper end being sted with a cup 1:, having a central hole rthrough its bottom. The said eu'p n is formed with ulterior as well as exterior screw-threads, so as to adjustably receive a needle-valve L, whose innction is to regulate the admission of water through the cup-opening r, the said needle-valve ll having a vertical bore p t-hcrct-hrough. The block K is further formed with a horizontal bore q entirely therethrough, and in lltfl communication with the yertical bore in. M represents a llexible washer or pat-kin disk, surrounding said dink ha ng its periphery turned downward around ,the upper edge of the block proper, and damper to place by a block I\', of a. diameter small enough to move freely within the. shell or casing D, said block N having a central screw-threaded bore to reccive and on we .with the cxtcriorly'scicwthreaded nee I? of the block K. The to i of the casin cap 0, w ich, as shown, may have a rubber knob 0 against which the hinged closet-seat, if one is emplo ed, may strike when raised, or the said knob may be located,'if preferred, upon the raised rib of the duct 0, but as this is innnaterial, I have not deemed it necessar to show any closet-seat inthe drawings. eferring next to the auxiliary or release valve, the outer casing G 'of saidyalve is herein shown as being cast into roll with a late g, and the latter pvrovide wit screwoles whereby it may readily secured to any desired place, which, in the present illustration, is shown as the floor of the room in which the closet is located, and just in front, and at one side ofjtho bowl A, so as to be OPGI'BtGa-HS a foot valve-although if preferred it 'niay=be otherwise located, so as by hand. P represents an inner Ofl8]!!g,01 shell, whose exterior surface the neck I: of sold bloc-ii,

D is closed by a properly puc :ed 1

ml 1 in line and conunnnicating with said l water-works o a city, which may, for exznni corresponds generally to the interior surface of the outer casing (t, to which it is secured, as b the screw-tilreadcd connection shown in Fig. 4, the joints between the two casings G and P being protected by packing rings s s. The inner casing l has a c lindricol opening theretlu'ough the lower part of which, lieiuw' the line of the her inhel'ore named ductf in the outer casing (l, is reduccd in dimnet-er, its lower edge l'ounin the seat of the valve-plug Q, and the casing G is formed with an annzdar recess or chun duct ,and th casing l is formed with an annu ar series of perforations ua, comnumicat ing with said annular recess or channel t. The casing (I extends helow the line of the casing! so as to form a water-chainher It or greater diamete than the cylimlrical l)nl'( ol the casing: i. this chair-laul'i cominunicnting l'reelv with the lu-reinlu-l'ore named due-tc. The \':ll\ lt'; 'f Q is last on a rod S, the oilicr end ol which is seren threaded to receive a not 'l, n which there rests a llexilde washer or packing-dish l'. whose periphery is trrned dowmvard around the upper edge ol Bi l not, said disk lacing held in place on the valverod 5, l the prshpltct' \i', the latter hung a solid (1 lindcr havmg a central screw-tlireuded ln l'l' for attachment to the rod '75, and l)llll of a length to llulltlttllj' project he) ond the plane of the ctlsii'ig plate 1/, us lnmn.

The operation of my invention will he readily underst od from the l'ore :5oi!:; d scription of itsconstrurt ion, taken in connectioii with the accompanying drawings, in which the various parts are shown in their relative positions, ready for the flushing oporation. As alr ady stated the main l is to be understood as connected with the souri-c of water supplv under pressure, such as the ple, have a pressure :J-tiity pounds to the square inch. From said main the water under pressure has mss-wl through the hores q I and 111 of the hloc l\' of the main valve, and g up through the en r peuing 1', and the hurt 2 in the. needle-va \'e l, into the upper )ortion of the, casing l), lilling the space there and flowing out through the ducts c, (I, and {MW-pipe to and through duct. 1' in the auxiliary valve casing (2 and filling the \\'t1lll chamber R in said casing, which (as a l this 2 water is under-the described prcssu'm,amlas there. is no water under any other than atznusphcric pressure in the cylinder B, pi e l and (mullet-thins) will keep the anxi iary l valve-plug Q against its seat at the base of t the inner easing I. Now, if it is desired to flush the bowl A, it, isonlv neeessaiy to H058 the push-piece V, so as to free said aux: iary or release valve plug Q. The moment this is done, the water under pressure will flow up 3 from the wtttltl t'lltllllllll li into he bore of i the casing P and out through the srfora Lions 1:, u, and recess or channel tan ductf into and through the return pi e F and duct b, and down through the ey inder B, and howl A, causing the water in the upper end of the casing to tlow outward through the duct t", and thereby instantly reducing the pressure in said water in said upper end of the casing 1), whereby the stronger pressure of the water from the main I will instantly force the l)l()(l( K and its attached parts upward. thereby lifting the main valve plug J from its seat, and permitting the water under pressure from the main l to rush down through the cylinder B, and llu h the howl A. As soon as the auxiliary valve-plug Q is closed again (which is done by the pressure of the water in chamber It against the disk U and said plug Q, when the iush-picc-e is released from pressure) furl hcr tlow of water from the casing D and flow pine E is at once sto )pcd, and then the block li, with its attaclunents, begins to descend by gravity, aided by the pressure of the water in the up- )tl end oi said casing l) on the l)l()(k K. As long as the main valve is open, water is continually passing a through the always open bore 1' in the neet evalve 1;, so that there is never any vacuum in said upper end of the. casing l) -'-hove the block N, llll volume of water therein contained depending upon the position of the main valve.

A great advantage of my construction lies in the entire ahsence ol' sprin s and lovers in hoih the main and the auxiliary valve and with the inlltt, should re air become necessary, Ila-n l) reason of t .e construction of the described inner casin" P, the same with the push-piece, valve-rod, and valveplug, can all he removed bodily, by inserting a.-

)roper tool, such as a spanner, or compasses, in the holes 1' t In the top of Sttltl casing P,

and this is especially convenient and desir-.-." able, as lllcrclv, the valve-seat (which is the lower end of the casing l) is withdrawn with the valve. thus obviating the-necessity of grinding down the valve-seat, as might be necessary if the valve-seat remained in the stationary casing which was fixed to tho lloor or other structure.

As a matter of convenience, I term the described parts and attachments of my main valve, taken collectively, as the lunger, this including the blocks K and N, interposed llexihle disk M, cup 11 and needle-valve L, as well as the valve-plug J; and similarly, l term the inner movable parts (push-pious Y, packingalisk U, nut 'l, valve-rod S, and plug Q) of the auxiliary valve, when taken eollectively, the core.

.\nnthet advantage of my invention lies in the fact that the said danger of my main valve is always surroum ed by water undo! pressure, whether said valve [5 onen or l closed, whereby all danger or liability of bored bloc r,

-21 reduced lower part,

'versel leakage between the packin -disk M and the 'main valve cusin" is entire y obviated, and

further. with my 1 cvicc, the main and auxiliary valves are wholly nidcpcndcnt in loca tion, and may be segmut-cd to any distance required which is of great advantage in many cases.

Having thus described my invention, what I claim as new, and desire to secureby Lettars-Patent, is

1. The combination with :i casing having forming a valve seat, a removable top, kind an inlet pipe, above the valve-seat, for connection with the source of water-supply, of u plun er and valve freely and vertica ly movable 1n the upper part of said casin and comprising a' transversely with u. communicating vertical bore, and an upward extending neck, a flexible disk surrounding said neck and forming a packin anothcr block, also surrounding said nec and clamping said packing disk to place. a 'cup closing the upper end of said vex-tics bore and hiiving a. central opening in its boriom, a needle vulve formed with a vertical bore therethrough and udjustubly scoured within. said cup, and a valve-plug rigidly secured to the underside of said tronsand v t-tically bored block; a {low pipe ending from the upper part of said casing above said vnlvm and 11 return pipe leading to the lower partof said casing below said valve-seat.

2. An outer valve casing having a wntcr chamber in its lower part and :1 duct leudin" thereto from the outside, the interior of said reduced part being formed with an annular 1 recess or channel, and u communicating duct lending outwardly through said ctrsin', in combination with an inner casing w rose exterior conforms substantially to the interior configurutii'in of said outer casing, and which has a vertical bore therethrough, reduced in diameter at its lower end here said inner casing is rcmovnbly connected to the outcr casing, jus above the water-chamber in the latter, mid an annular series of openings in lino and connnnnicnting with the annular recess in the outer casing, the joints bet-ween the two casings bein suitably packed; a push-piece havirw vertlcal movement within the bore of t 1e inner casing; a valve rod. secured to said push-piece and depending into said nter chamber; a nut on said rod, and u. flexible puckin disk int-erposed bctwcen suidnut and pus i-piece; and

a valve-plug on the lower end of said valverod.

In testimony that I claim the fore oing I have hcrcunto sct my hand at Milwariliee, in the county of Milwaukee and State of Wisconsin the presence of two w tnesses,
